lilILK-GAN CLEANER AND STERILIZER.

" Application med February 14, 1922. Serial No. 536,439.

To all whom it may concern."- Be it known that I, JAMES A. DARY, a .citizen of the United States, residing at Ottawa, in the county of Franklin, State I of Kansas, have invented anew and use- .ful Milk-Can Cleaner and Sterilizer;v and I do hereby declare the following tobe [a full, clear, and exact descri tion of the invention, such as will enab e others skilled and use the same;

The-invention relates to can cleaners and sterilizers,particularly adapted for use in connection with cleaning and sterilizing milk cans at receiving stations by applying steam tothe interior and exteriorof the can 1 simultaneously, thereby sterilizing the can, j and atthe same time dislodging cream from a the interior thereof. Also to provide means 10 whereby veyed to receptacles. v

A further object is to p .fivide a liquid vaporizer for steaming milk fcans, said vapori'zing comprising a steam drum into which hmited amou'ntsof water are passed,

vaporized and allowed to pass into engagement with the interior walls of thefmilk can and the exterior walls thereof, fandto A further object is to provide av liquid supply tank in connection with the steam drum through the medium' of a, pipe said pipe having valve vmeans whereby the flow t I of water through the pipe may be controlled.

Also to provide inconnection with the liquid supply tank a pipe havinga coil-extending around the steam drum in such amanner that, the-liquid within the tank will be maintained heated by the steam drum and 4o the heating element.

"A further object is to provide in con}, nection with the device a canwashing sink,

I i which, sinkl has in' connectio1itherewith a i coil extendingar'ound the steam drum therejelement, i em-d beneath the ;-d1'-um',j to be utilized for maintaining the water within the sink heated.

' With the above and it appertains to make the dislodged creanijiwill be conview the invention resides in the,co mbina'-' 'tion and arrangement of parts as hereinafter set forth, shown in the drawings, described, and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed w'thout departing from the spirit of the invention.

In the drawings Figure 1 is a toppla'n view of the device.

Figure 2 is a vertical longitudinal sectional view through the device. t

Figure 3 is an end elevation of the dei Figure 4 is a vertical sectional view through the steam drum.

Figure 5 is a horizontal sectional view through the steam drum taken on line5 5 of Figure 4. r r i Figure 6 is a perspective view of portions of the perforated pipes within the cylindrical can receiving member.

Referring to the drawings, the numeral :1 designates a table, which. table is supported on legs '2. The legs 2 and the table 1 also.

support a sink 3, in which cans may be washed asdesired. The water in the sink 3 is maintained heated by means of the pipe 5, which is connectedatfi to the sink, and is provided with a coil'7 whichextends around the steam drum 8 andthroughwhich pipe -5 and coil'7, the water from the sink 3 passes and-returns tothefsi'nk at 9. It

,will be seen that when the heating element 10, which may be a lamp or "any other form of heating element; is in operation, that the heat therefrom may pass upwardly throu h- .thev chamber llof the casing 12iand will maintain the coil 7 heated, thereby causing a circulation of water from thevsink 3, which during its U circulation will be maintained hot forcan washing purposes.

Disposed beneath the table 1. is a water "supply tank 13, and extending, downwardly from. said tank 13 is a pipe 14,.wl1'ich Y ipe enters the-upper endof'the steam ome 10! 8V at 15 and terminates in outwardly extend- '1v 7 ing arms 16'through which water in" re'de termined ;quantities'- passes and is orceu;

in engagement-with the inner wall 17 of the steam drum 8 where'it is vaporized b the heat of the drum and the heat from thelieating element 10. After the water has been vaporized it passes upwardly through the pipef18 and is discharged through the end 19 of said pipe at a point where it will enter the interior of a milk can inverted and sup ported over the end 19 of the ipe 18. The amount of water allowed to ow" into the steam drum 8 is controlled by means of the valve 20, which'valve is operated by the connecting rod 21, the lower end of which is connected at 22 to the valve lever 23 and the upper end connected'at 24 to the rockable operating lever 25. In practice it has been found that by allowing about one ounce of water to enter a steam drum 8 all of said water quickly vaporizes and is of a'sufficiently high temperature to sterilize the interior of the can through pipe 19 and the exterior thereof through the pipe 26, the? upper end of which terminates in a vertically' disposed perforated pipe 27 having pivotally mounted thereon to swing in a horizontal plane segmentally shaped perforated pipes'28, communicating vwith the perforations 27 in, pipe 27, which pipes 28.

are threaded at 28 to the pipes 26 and'27.

' Bushing 28 connects the adjacent ends of the sleeves 28, however it does not overlie the inner ends of the pipes 28, therefore it will be seen that steam will pass through the pipe'26, the sleeves 28, bushing 28 to the perforated pipes 27 and 28. The casing 29 is preferably formed from twosegmentally' shaped sections 30 to which are secured the segm'entally shaped pipes 28 at 31, which allows the casing 29 to beeasily and quick ly opened for placing a milk can to be cleaned and sterilized therein. Ithas been found that it is desirable toheat the water within the supply tank 131 To accomplish this result the pipe- 32 is connected to the tank 13 at 33, which pipe extends down-'- wardly and is provided with a coil-34 exthat the water within the tank 13 will have a tending around the steam drum 8, and

vthrough whichcoihwater from the supplytank 13 passes and is heated bythe drum 8 and the heating element 10, and-"then passes back into the tank 13atz35: It will be seen that" a continuous circulation of water from the tank 13 is maintained and high temperature before it enters the vaporizing drum 8, thereby insurlng quick and rapid vaporization of the water. If water should collect within the drum .8, it may be easily and quickly removed by opening the valve 36 carried by the drain pipe 37. The

top 38 of the table 1 is provided with an opening 39 over -which the mouth of the milk can is disposed, in such 'a manner that the steam passing outwardly from the end 19 of the steam pipe 18 will enter the interior of the can substantially centrally thereof. Extending downwardly from the under side of the table top 38 and in registration with the opening 39 in the table top is a conically shaped annular member 40, the lower end of which terminates in a downwardly and outwardly extending tubularv portion 41, which terminates adjacent one side of the device and preferably abovethe supporting platform 42 on which a receptacle 43 is supported. It will be seen that cream which is dislodged from the interior of the milk can by the steam will be conveyed downwardly and outwardly and discharged into a receptacle, and consequently saved. 1

It -will be seen that a milk can sterilizer and cleaning device is provided, wherein steam is used and that the device is' so constructed that the danger of explosion is absolutely eliminated, and no matter how much water is allowed to enter the steam drum 8, when the same is expanded or vaporized,

it will immediately pass upwardly through.

tion of external and internal heat on the walls of the can. It has been found that the application of heat to the outer face of the can more readily and quickly dislodges cream from the inner face of the can, than the direct application of internal heat only. I The .water supply tank 13 is provided with a filling pipe 44 normallv closed by the plug 45, and through which, filling pipe water may be placed in the supply tank 13. The

segmentally shaped sections 30 are provided with handles 46 adapted to'be grasped by the operator in opening and closing, the

casing 29, when placing a can in position or removing the same. r
